This contribution addresses limits and pitfalls of a common NiTi macroscopic modeling shortcut: neglecting experimentally documented specifics as tension-compression asymmetry or anisotropy of some physical properties of martensite. It is shown that an accurate prediction of NiTi wire response in torsion can be obtained with parameters derived from a test in tension and compression, which challenges the general comprehension of the influence of the processing texture.
